CARL G. PAINGEL, OF BUTTE, MONTANA.

ORE-CONCENTRATOR.

SPECIFICATION forming part of Letters Patent No. 516,021, dated March 6,1894.

Application led June 14:, 1893. Serial No. 477.583. (No model.)

To all whom it may concern,.-

- Be it known that l, CARL G. PINGEL, of Butte city, in the county of Silver Bow and State of Montana, have invented a new and Improved Gre-Concentrator, of which the following is a full, clear, and exact description.

The invention relates to placer mining appliances, and its object is to provide a new and improved ore concentrator, which is comparatively simple in construction and very eective Vin operation.

The invention consists principally of a bowl having a rotary and jigging motion and provided with a spout discharging into al jigging sluice.

will be hereinafter described and then pointed Y out in the claims.

Reference is to be had to the accompanying drawings, forming a part ci this specification, in which similar letters of reference indicate corresponding parts in all the gures.

Figure 1 is aside elevation of the improvement. Fig. 2 is a plan View of the same. Fig. 3 is an enlarged sectional side elevation of the improvement. Fig. a is a transverse section of part of the sluice on the line E-a of Fig. 8. Fig. 5 is a plan View of the track for the revolving bowl; and Fig. 6 is a plan view of the shaft connection with the bowl.

`The improved ore concentrator is provided with a suitably-constructed frame A in which is journaled the vertically-disposed shaft B carrying a pulley B connected by a belt C with a driving pulley C rotated either by hand or by power, as desired, so that a rotary motion is imparted to the shaft B. The upper end of the shaft B is provided with an elongated and rounded head B2 fitted into a correspondinglyeshaped socket D arranged on the under side and in the middle of a bowlE carrying on its bottom a number of wheels F adapted to travel on a track G having a series of inclines with abrupt steps so that the wheels F drop ed the upper ends of the inclines onto the lower part of the next following inclines thus imparting a jigging motion to the revolving bowl E carried around by the shait B.

The ore to be concentrated is placed in a hopper H supported by inwardly and upwardly extending bracket arms Il from the upper edge of the bowl E, the said bracket arms supporting the hopper centrally over the bowl so that the sand beari ng the precious metal passes directly into the bowl. The lower part and bottom of the hopper H is preferably made as a screen, as illustrated at H2 in Fig. 8, so as .to retain heavylurnps and to permit of passing only sand and ne, precious metals, into the bowl E.

In order to facilitate the washing of the sand and ore in the bowl, a stream of water is continuously discharged through a pipe I into the top of the hopper H. The bowl is preferably made of iron having a copper bottom, and at the junction'ot the copper and iron is arranged an inwardly and downward- 1yr-extending,` annular ria-nge J, which serves to prevent the quicksilver in the bottom oi' the bowl from escaping with the waste and dirt which is thrown off over the edge of the bowl into an annular gutter K surrounding the upper edge of the bowl and firmly supported by suitable brackets attached to the track G or the upper part of the frame A. In the gutter K is arranged a downwardly-extending spout K which discharges into an inclined jigging sluice L. The jigging sluice L consists of a fixed frame L', supported at its upper end on a projection A forming part of the main frame A, and at its lower end on a standard A2, and a second frame N fitted to slide vertically in the fixed frame L. The frame N is provided near its upper and lower ends with vertical slots N", through which pass the rods L2 secured in the sides of the xed traine L. frame N is made of a corrugated copper plate to form rilies for the retention of the precious metal contained in the discharge from the bowl E.

In order to impart a vertical j igging motion to the second frame N, I provide the same with sets of friction wheels l? and P engaged by sets of cams Q and Q respectively, se cured on transversely extending shafts R and R respectively, journaled in suitable bearings in the sides of the xed frame L. The shafts R and R carry pulleys R2 and R3 repectively, connected with each. other by a The bottom O of this second A IOO belt R4 and on the shaft R is secured a second pulley S, connected by a belt S with a Y pulley S2 on the revoluble shaft B.

'The operation is as follows: Nhenthe main driving shat is rotated, a rotary motion is transmitted by its head B2 to the bowl E, which, on account of the wheels F dropping off the ends of the inclines on the track Gr, re-

ceives a jigging motion, so that the waste and dirt contained in the material under treatment Within the bowl is thrown oft the upper edge of the bowlinto the gutter K from which the said material passes into the spout K and'down the same into the jigging sluice L. The spout K discharges the material into the uppermost riffie formed by the corrugated bottom O and as the frame N supportingthe said riftles has a jigging motion, thematerial is jigged from one ritl'ie to the next lower one, whereby the heavy precious metals are retained in the bottom of the riiiies, while the Vtailings pass from one riffle tothe other to be finally discharged over the lower-most riiiie. It 1s understood that the rotary motion of the shaft B imparts by the pulleys S2 and S, and the belt` S', a rotary motion to the shaft R', which, by its connection with the shaft R rotates Vthe latter so that both sets of cams Q and Q simultaneously impart a jigging motion to the sliding frame N con taining the riiiies. As

n previously described, the annular flange J retains the quicksilver in the bottom of the bowl E, and after the operation hasbeen cono tinued for a certain length of time and the precious metal retained and amalgamated in the bottom of the bowl E, then the said material is drawn oit from the bowl through a capped outlet E in the bottom of the said bowl. It is understood that during this operation the machine is held at a standstill.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. An ore coucentrator, comprising a bowl provided on its under side with wheels, a shaft having a loose connection with the said bowl for rotating the same and permitting the same to tilt, and a track having inclines on which travel the said Wheels, substantiall y as shown and described.

2. An ore coucentrator, comprising a bowl provided on its under side with wheels, a shafthaving a loose connection with the said bowl for rotating the same and permitting the same to tilt, a track having inclines on which travel the said wheels, and a fixed annular gutter surrounding thefupper edge of the said bowl and provided'with an outlet spout, substantially as shown and described.

3. An ore coucentrator, comprising a bowl provided on its under side with wheels, a shaft having a loose connection with the said bowl for rotating the same and permitting the same to tilt, a track Vhaving'inclines on which travel the said wheels, and an annular ond frame in the Xed frame, having a riftled bottom and provided with vertical slots at its ends,`rods passing through the said slots and secured to the fixed frame, rollers or wheels on the second frame, and cams below the rollers or wheels and engaging the same, substantially as described.

G. An ore coucentrator, comprising a bowl having a rotary and jigging motion and provided with an annular gutter at its upper .edge and a spout leading therefrom, an inclined sluice having a riftled bottom and arranged below the spout and into which the said spout discharges, and means for imparting an up and down motion bodily to said sluice, substantially as described.

7. An ore coucentrator, comprising a bowl provided with an annular gutter and a spout leading therefrom, means for imparting a rotary and a jigging motion to the bowl, an inclined sluice having a corrugated bottom, into which the spout discharges, and means for impartinga jigging motion to the sluice, said y means being operated from the bowl operating shaft, substantially as herein shown and described.
